[PHP] Submit Using An Image Form Processing

[Ron Piggott]

I am writing a shopping cart using the PayPal API.  Shopping cart works.  Just 
adding additional functionality.  

>From the shopping cart contents I am trying to make it so the user may click 
>on a picture of a trash can to delete the item.  I wrote the following line of 
>code:

<INPUT TYPE="image" 
SRC="http://www.theverseoftheday.info/store-images/trash_can.png"; WIDTH="20"  
HEIGHT="20" style="float: right;boarder: 0;" alt="Remove Product From Shopping 
Cart" name="remove_product" value="1" />

But when I have do:

echo $remove_product;

I am not getting anything.  Is there a correct way of passing a variable 
through an image?  The value in this above example is the auto_increment value 
of the product.  From this I could remove the item from the shopping cart.  

OR

Is there a better way to pass a variable through a graphic?  I am hoping for 
the shopping cart contents to be just 1 form where users will have several 
options (change quantities, delete specific items).  I can’t use a hidden 
field.  

Thank you for your help.
